The Voice of the DBA

Valentines Day for Data Professionals

It's Valentine's Day today, and if you've forgotten, you still have time to do a little shopping or show your partner that you value them. While this isn't a public holiday in any country that I know of, many people do want to celebrate with someone special to them. In fact, if you forget about this day, chances are the next few might not be so pleasant.

For many of us, we'll spend nearly as much time at work each week as we might spend with our families. Between a few extra hours here and there at work, commuting, and sleep, it may often feel like we spend more time at work. Hopefully that's not the case, and if it is, you should re-evaluate your current position.

Most of us do have a relationship with our career. We've chosen it for some reason and are often locked into doing certain work in the short term. With today being a relationship holiday, I wanted to ask you to think about if you really love your career?

I'm not speaking about your current job and employer. You might enjoy being a developer, DBA, or other data professional while not being enamored with the position and place you work now. I'm asking for the long term, are you happy with your career choice and looking to continue moving on this path.

If you are, good for you, and I hope you find a great position that suits your life. If not, it doesn't matter what you've done in the past. You can start moving forward in another direction today.

I love my job, and I've enjoyed the last 25 years of working with SQL Server. I don't know if I want to do another 25, but I certainly am still in love with my choice today.

Yesterday's Question (by Steve Jones):

On SQL Server 2016, what is the data type of a parameter for SET CONTEXT_INFO?

Answer: binary data

Explanation:

SET CONTEXT_INFO needs varbinary(128) data passed in. Other data types need to be implicitly CASTed or CONVERTed to this type. The implicit conversions occur with numeric types
